需求需要做一个如下图的金字塔,上面的字就不需要了,只建好金字塔的模型即可。现我已经用html5建好一个三角形,求给个完成金字塔的思路,若有代码就更好了.
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
<title>MYJZT</title>
<body onload="draw('canvas')">
<div style="text-align:center;">
<canvas id="myCanvas" width="400" height="500" solid #c3c3c3;"></canvas>
<script type="text/javascript">
var c=document.getElementById("myCanvas");
var cxt=c.getContext("2d");
cxt.strokeStyle="black";
cxt.beginPath();
cxt.moveTo(200,0);
cxt.lineTo(0,400);
cxt.lineTo(400,400);
cxt.lineTo(200,0);
cxt.moveto(150,50);
cxt.line(50,200);
cxt.closePath();
cxt.stroke();
</script>
</body>
</head>
</html>
这些代码是我绘制三角形的。
<head>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
<title>MYJZT</title>
<body onload="draw('canvas')">
<div style="text-align:center;">
<canvas id="myCanvas" width="400" height="500" solid #c3c3c3;"></canvas>
<script type="text/javascript">
var c=document.getElementById("myCanvas");
var cxt=c.getContext("2d");
cxt.strokeStyle="black";
cxt.beginPath();
cxt.moveTo(200,0);
cxt.lineTo(0,400);
cxt.lineTo(400,400);
cxt.lineTo(200,0);
cxt.moveTo(200,0);
cxt.lineTo(50,200);
cxt.lineTo(0,400);
cxt.moveTo(200,0);
cxt.lineTo(350,200);
cxt.lineTo(400,400);
cxt.closePath();
cxt.stroke();
</script>
</body>
</head>
</html> 参考技术B 在右边在绘制一条直线,角度和右边的棱大约25°,要稍微短一些,然后连接

运行效果:
<!DOCTYPE html> <html> <head> </head> <body> <canvas id="drawing" width="800" height="600">A drawing of someing!</canvas> <script type="text/javascript"> var drawing = document.getElementById(\'drawing\'); if(drawing.getContext) { //绘制立体文字 var context = drawing.getContext(\'2d\'); context.fillStyle = \'Purple\'; context.textAlign = \'center\'; context.textBaseline = \'middle\'; context.font = \'bold 100px Arial\'; context.fillText(\'莫\', 290, 90); context.globalAlpha = 0.7; context.font = \'bold 80px Arial\'; context.fillText(\'欺\', 380, 90); context.globalAlpha = 0.6; context.font = \'bold 70px Arial\'; context.fillText(\'欺\', 205, 90); context.globalAlpha = 0.6; context.font = \'bold 60px Arial\'; context.fillText(\'少\', 450, 90); context.globalAlpha = 0.5; context.font = \'bold 60px Arial\'; context.fillText(\'少\', 140, 90); context.globalAlpha = 0.5; context.font = \'bold 40px Arial\'; context.fillText(\'年\', 500, 90); context.globalAlpha = 0.4; context.font = \'bold 40px Arial\'; context.fillText(\'年\', 95, 90); context.globalAlpha = 0.4; context.font = \'bold 20px Arial\'; context.fillText(\'穷\', 530, 90); context.globalAlpha = 0.3; context.font = \'bold 20px Arial\'; context.fillText(\'穷\', 65, 90); context.globalAlpha = 0.3; } </script> </body> </html>
